Thinking About Composting? This Is Your Ultimate Guide (Re-Post from Food.52)

Thinking About Composting? This Is Your Ultimate Guide (Re-Post from Food.52)

May 10, 2021

Your plants, the earth, and your garbage can will thank you.

It’s always gross when you go to take out the trash, only to find the bag smells like rotting food—and maybe is even dripping from the bottom. Bleck. But what if I told you there was a way to prevent your trash from smelling, all while being more eco-friendly in the process? Sign me up!

Composting offers both these noteworthy benefits, not to mention that it creates rich fertilizer that your gardens or houseplants will love. (Seriously, people call it “black gold”!) However, I didn’t know the first thing about composting—not to mention how I could do it in my apartment—so I called in an expert: Erin Rhoads, an eco-lifestyle blogger and the author of Waste Not, a guide on how to make a big difference by throwing away less.

Here’s what she had to say about all my pressing composting questions.

Why Compost In The First Place?

"When we compost organics like food, they’re no longer waste," explains Rhoads. "Instead, they become food for soil. Our food, the unprocessed stuff, is designed to break down in soil where all types of insects, bugs, and worms will eat it up, helping return nutrients to the soil while improving its quality."

The end result is nutrient-rich soil that your houseplants or garden will absolutely love.

Another benefit of composting is that it makes your trash less stinky—if you’re putting all of the food waste into the compost, there won’t be any rotting items in your garbage bin. Finally, composting reduces the production of a common greenhouse gas and helps minimize use of chemical fertilizers.

"Starting a compost not only cuts down rubbish sent to landfill, it’ll help cut down on methane gas, and reduce reliance on artificial fertilizers, which is another money saver,” she says. “Composting is a win-win!”

What Can Go In My Compost Bin?

According to Rhoads, compostable items are commonly broken down into “green” and “brown” categories. Green items are plant-based, wet materials, including:

  • Fruit and vegetable scraps
  • Grass clippings
  • Plant trimmings
  • Weeds that haven’t gone to seed
  • Animal manure, but only from “vegetarians” such as cows, sheep, chickens, and rabbits

Brown items, on the other hand, are dry plant material, such as:

  • Dried leaves and twigs
  • Straw, hay, or corn stalks
  • Paper, such as newspaper, coffee filters, or paper tableware
  • Sawdust
  • Corrugated cardboard

Plus, there are some items that can’t go in your compost bin at all:

  • Meat and dairy products, which can attract pests
  • Fats, grease, lard, or oils
  • Glossy paper or cardboard

For a more comprehensive breakdown, check out the Environmental Protection Agency guidelines.

Any Common Mistakes I Should Know About?

Composting is all about balance, and Rhoads says it can take a little practice to get it right.

"The most common mistake when it comes to composting is not maintaining a balance between the green and brown matter," she explains. "An oversupply of the green stuff—food scraps, green leaves, grass clippings—will not break down properly. Alternately, too much brown waste, like newspaper and brown paper, brown leaves, branches and twigs, slows down the process."

You’ll also want to keep your compost from drying out: "If your compost becomes too dry, spray lightly with water."


How Do I Maintain The Balance?

It’s actually pretty straightforward.

"Keep the balance between green and brown by adding the same amount of both at the same time," Rhoads recommends. "Turning your compost regularly with a shovel or compost turner promotes the circulation of oxygen. This is key to reducing funny smells, too!"

The 1:1 ratio is just a suggestion, so don’t worry too much about having exact amounts of green and brown materials. However, if you find yourself with way too much of one type, you can either hold off on adding it until you can balance it out, or simply ask a friend or neighbor if they have any materials for you.

What Can I Compost That I Might Not Know About?

Don’t believe everything you hear about composting. Rhoads says there are several items people think can’t be composted, but actually can!

“There is the myth that lemon peels can't be composted, but really they can, so long as you are not putting too much in, especially when you are using a worm farm,” she explains. “Coffee grounds can be added to the compost, as can pizza boxes, but tear them up to make it easier to break down.”

You can even compost pet waste, but you need to do it separately from your normal pile: “Hair, nail clippings and even pet fur will break down in a compost. If you have pets, consider starting a designated compost for their waste, too.” The USDA has a thorough guide on how to compost pet waste.


Can I Compost Indoors?

Not all of us have an outdoor space where we can compost—I live in an apartment, but I’d love to get in on the action.

Lucky for me, countertop composting products are becoming increasingly common, making the practice more accessible.

“I've seen a rise in worm farms being used indoors disguised within seats inside kitchens!” says Rhoads. “You might think it will smell, but like any compost or worm farm, once the balance is right there will be no smell.”

There are also crowdsourced composting groups, which allow you to work with your neighbors to reduce waste, like one Rhoads recommends called ShareWaste. "This is a website and app that connects people who wish to recycle their kitchen scraps with their neighbors who are already composting, worm-farming, or keeping chickens."

How Long Does Composting Take?

So you’ve made a compost pile and put in your greens and browns… then what? Essentially, you wait. In a well-maintained compost pile, decomposition can take anywhere from two to four months, but there are numerous factors that affect this timeline, such as the time of year. As Rhoads mentioned, too many browns can slow the decomposition process, and you’ll also need to be diligent about wetting the pile if it dries out and turning it once a week or so.

How do you know when it’s ready to be used? Your compost should look and feel like rich, dark earth—not rotting vegetables! If you see large chunks of food waste or it has a sour odor, it’s not finished yet.


What Can I Do With Finished Compost?

Once your compost has sufficiently decomposed, you can use the beautiful “black gold” in several ways. Many people use finished compost as mulch, spreading it over their garden beds to feed nutrients to the plants and prevent weeds from growing. It can also be used to amend soil in your gardens—mix it into your beds before adding plants or seeds to give them a nutrient boost.

No outdoor gardens? No worries! Your houseplants will love compost, too. Just mix compost into your favorite potting soil and use it to repot your indoor plants. They’re sure to appreciate the rich growing medium.

There’s also a concept called “compost tea,” which is exactly what it sounds like—just don’t drink it! To make tea, you soak compost in water for three days—a 5:1 ratio of water to compost is recommended—then strain out the solids. The resulting liquid can be sprayed onto your plants or garden best as a fertilizer. It’s a great way to stretch a little bit of compost farther.
